FOUNTAIN PEN.

Application filed. January 30,1924. Serial No. 689,540.

The present invention relates to fountain pens and particularly to that type known as self filling pens.

The principal object of .the invention is to generally improve upon the self vfilllng features thereof so to provide a simple and efficient construction which will be reliable and well adapted to the purpose for which it is designed. I

With the. aboveand numerous other objects in-view as will appear as the description progresses, the invention resides 1n certain novel, features of construction and in the combination and arrangement of parts as will be hereinafter more fully described and claimed.

In the drawing: I t Figure 1 is a longitudinal section through the preferred embodiment of my self filling 2o fountain pen, 7 I

Figure 2 is atransverse section therethrough taken substantially on the line 2 2 of Figure 1 looking in thedirection of the arrow.

Referring to the drawing in detail, it will be seen that the preferred embodiment of. my fountain pen includes a barrell and a casing 2, the casing 2 being threadedly mounted on the barrel l as at 8 soas to be disposed in longitudinal alinement therewith. The end 4 of the barrell is provided with anopening in which theend 5 of the collapsible sack 6 extends and is secured. Compression means for this sack 6 is provided in conjunction with the casing 2 and consists of an elongated loop member? terminating in a pintle 8 towhich is hinged an arm 9. The normal;

position of this arm'is shown in Figure 1 andit will be readily understood thatit collapsible sack 6.1 When the arm 9 is re leased this collapsible sack will return to its normal position so asto draw ink into the reservoir of barrel 1. The collapsible sack 6 is so constructed and, arranged that it will only draw in enough ink to fill the reservoir in the barrel 1 and the sack itself is' not adapted to be filled. Thus, the sack is not designed for holding ink but simply serves as a means for drawing the ink into the reservolr of the barrel. sack is not continuously filled wlth ink sack is therefore not subjected to the deteriorating effects of the ink so that it is not liable to become quickly rotted.

the collapsible sack, con'iprising an elon-- 4 gated loop disposed in the casingbeside the 4.0 may be swung to the dotted line position in v collapsible sackandterminating at one side of its outerjend in a longitudinal pintle journaledthrough the outer end of the casing, and an arm. hinged to said pintle whereby it may be rotated for swinging the elongated loop to compress the collapsible sack, said arm normally overlyingthe end of the casing and be ng movable to a position wherein the same projects laterally outwardly beyond a side of the casing for fa cilitating its actuation.

. In testimonywhereof I aflix my signature.
